Among SLE patients, mRNA levels of MX1 (median: 453.40, IQR 200.85–973.45 vs. 968, IQR 284.90–2380.75) were slightly lower in those who were anti-DNA (−) than in those who did not: however, the differences were not significant (Supplementary Table 4). The gene discussed is MX1; the disease is systemic lupus erythematosus.
